Gelest Announced Diiodosilane Commercialization

Jul 2018
MORRISVILLE, Pa., July 27, 2018 — Semiconductor material Gelest Inc. has announced the commercializing of diiodosilane to meet the global demand of the semiconductor industry for next-generation semiconductor chips.

Gelest’s dedicated diiodosilane plant in Morrisville is fully operational and can produce commercial quantities of diiodosilane with purity in excess of 99.9 percent. Diiodosilane is a key chemical precursor used by semiconductor companies worldwide in the development and scale-up of next-generation semiconductor chips that require high-throughput, highly conformal silicon nitride thin films.

Diiodosilane is typically deposited by plasma-enhanced atomic layer deposition to create the silicon nitride thin film. Gelest sees a significant increase in demand for high purity diiodosilane driven by development and production of semiconductor chips requiring silicon nitride thin films at low thermal budgets.

Gelest is a manufacturer of specialty materials for the semiconductor industry.


GLOSSARY
thin film
A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
